This invention relates to a luminousadvertising device comprising afront portion provided with freely standing characters or (and) signscut out or stamped out and constituting advertising matter, anilluminated concave rear wall located behind said advertising matter,and a source, or sources, of light arranged between the said matterandthe rear wall in such a manner that it is, or they are, invisible forpersons looking at the advertising device.

I am aware of the existence of luminous advertising devices showingadvertising matter consisting of opaque characters or (and) signsapp'earing as silhouettes in front of an illuminated background. Thereareamong these known devices such, the background or rear wall of whichis vaulted similar to the circumferential surface of a cylinder and isso arranged that the appertaining axis of the cylinder extendshorizontally. I

The present invention relates to an improved 1 construction of luminousadvertising devices of pbesides, as a decoration means.

the just mentioned type, and consists therein that the illuminated rearwall serves also as carrier for figurative representations in that itsupper rim is cut out or stamped out in conformity with the contours ofthe respective representations. Another characteristic feature of theinvention is that the rear wall which is vaulted like thecircumferential wall of a cylinder is so arranged that the appertainingaxis of the cylinder extends vertically.

While the known luminous advertising devices mentioned in the abovefirst twoparagraphs are not suited for the decoration of store windowsand are to be mounted especially by reason of their unsuited design ofthe rear wall and the horizontal position of the axis of the curvatureof this wall only in a comparatively high position with respect to thelockers-on, for instance firmly fixed to the front of the respectivebuilding, the present improved luminous advertising device is portableand permits, therefore, to be placed, for instance, into publicexhibition boxes, the interior of store windows and rooms and a lot ofother places where the device can serve, Owing to' the particular designof the rear wall, in that this shows figurative representations, asalready mentioned, the eyes of persons passing by or being present, asthe case may be, are attracted whereby the object of the device isattained.

' The invention is illustrated diagrammatically and by way of example onthe accompanying drawing on which Figure 1 is a front-view of theconstructional form selected,

Figure 2 is a longitudinal horizontal section through the same, and

Figure 3 is a cross-sectional elevation through the center of thedevice.

On the drawing, i denotes the front portion and 2 the concave rearportion or background.

The front portion carries-any desired plurality of characters forming awork (3) and extending freely upwards from the top of the portion l, asshown in Fig. 1. The characters (or, maybe, signs suited to the objectin view) are cut or stamped out and may, if desired, be made integralwith the member I or at least the top thereof. Below the characters etc.3 and the rear wall 2 is arranged the source of light which is, in theexample shown, an incandescent lamp 4.

Inthe example shown the characters 3 extend upwardly, in fact, from acommon supporting member (not visible) inserted into an upper slot 5(Fig. 2.) of a box 6, 1 forming the body of the front portion I Saidmember with its characters 3 may be exchangeable so as to permit theshowing of another advertising word or the like. The box 6, 7 maycomprise a frame 6 and a front plate I which is also utilised for theadvertising purpose, in that it shows either opaque characters etc. on atransparent ground or transparent characters etc. on an opaque ground,the respective characters etc. being in either case likewise illuminatedby the lamp 4.

The figurative representations extending upwardly from the rim of theconcave rear wall 2 are formed, in the example shown, by female heads 8cut out or stamped out in conformity with the outlines 9 of therespective heads. Also said wall 2 may be exchangeable so as to permitthe showing of other figurative representations. For this purpose thefront portion I is provided with lateral guide members I0 (Fig. 2).

The figurative representations 8- proper, that is to say, the surfaceportions enclosed by the outlines 9, may be painted upon the material ofthe wall 2 or may be printed thereon, or separately manufacturedrepresentations may be pasted onto the wall portions concerned.

The freely standing characters etc. 3 may be opaque or transparent, inwhich latter case they are illuminated also by the lamp 4, the rays ofwhich illuminate said characters etc. from behind.

I wish it to be understood that I do not limit myself to theconstructional form shown in the drawing which is to serve merely as anexample.

In the details departures are possible lying fully within the scope ofthis invention.

I claim: A luminous advertising device, comprising in 5 combination afront box-like frame, a partially transparent front plate adapted tobear advertising matter enclosed in the said frame, detached cut-outsigns such as letters extending upwards from the upper edge of theframe, a 0 concave rear wall, cut-out signs such as pictorialrepresentations of figures extending upwards from the upper edge of therear wall to a greater height than the signs extending upwards from thefront frame, the rear wall and the signs upstanding therefrom beingcurved about a vertical axis, and a source of light concealed betweenthe front frame and the lower portion of the rear wall to illuminate therear wall and the signs up-standing therefrom and also the partiallytransparent plate in the front frame.
